If your design can use more than one cycle to implement the CRC functionality, adding registers and retiming the design can help reduce area, improve performance, and reduce power utilization.

If your synthesis tool offers a retiming feature (such as the Intel® Quartus® Prime software Perform gate-level register retiming option), you can insert an extra bank of registers at the input and allow the retiming feature to move the registers for better results. You can also build the CRC unit half as wide and alternate between halves of the data in each clock cycle.
